Interference between One- and Two-Electron Channels in Resonant Inelastic X-Ray Scattering
Interference between scattering channels is observed in resonant inelastic x-ray scattering (RIXS) at the Ne K threshold. Final states with |2p-1np⟩ as the main configuration are populated via |1s-1n′p⟩ resonances, where large-amplitude one-electron (n′=n) channels interfere with small-amplitude two-electron (n′≠n) channels. The interference is manifested in an asymmetric line profile where the tw
